Genshin Impact: The Wanderer's Younger Brother Travels Teyvat with Lumine

Long ago, about five hundred years in the past, the Raiden Shogun decided to create a puppet. It would be granted the power of a Gnosis and become her substitute. At last, the Raiden Shogun succeeded in creating a puppet named Raiden Kunikuzushi. However, when she infused Raiden Kunikuzushi with the power of the Gnosis, she discovered that the puppet could not withstand such immense power. The Raiden Shogun did not give up. Instead, she decided to use her own body to make the necessary changes. After completing the modifications, the Raiden Shogun’s consciousness entered a place called the Plane of Euthymia, while her body came under the control of the will known as the Raiden Shogun. What no one knew was that some materials remained after the Raiden Shogun modified Raiden Kunikuzushi. Thinking it a waste to throw them away, she used them to create another puppet, named Raiden Mengxin. Perhaps the materials were insufficient, or some parts were missing. Mengxin seemed more childish and adorably clueless, with an innocent air about him. He also looked more like Raiden Makoto. In the end, the Raiden Shogun sealed Raiden Mengxin away alongside Kunikuzushi, sealing their powers as well. When Mengxin met Yae Miko, he was taken in by her honeyed words and became Lumine’s traveling companion. Eventually, Mengxin started to realize that something was increasingly off about Lumine. By the time he tried to run, it was already too late.
